Fire safety design of shopping complex was carried out using performance concept. Safety of occupants and fire fighters, restriction of burning and smoke damage area were designed and verified against fire scenarios. Considering the huge size of the shopping complex, the whole building was divided into two parts by locating a large atrium in the center. The atrium works to confine fire and smoke effect within one of them. By adopting this design, fire safety strategy could be greatly simplified. As to the evacuation of occupants, non-fire side of the building is expected to be a temporal refuge area (TRA). As to the fire-fighting design, we provided two fire-fighting bases (FFB) in alternative direction from fire area. As to the fire and smoke damage restriction, fire is confined in 1/6 of one floor. To prevent the smoke from spreading to the other side of fire nor to upper floor shops, atrium is equipped with natural vent large enough to exhaust all the smoke. The structural stability was designed to prevent collapse during the whole process of fire to premise the above strategies.
